No Brewing. Application filed February 9, 1920.

To all 407mm iii-17mg concern.

Be it known that l, FRANK lllolnrnmrs, a citizen of the United States,residing at Toledo, county of Lucas, State of Ghio, have invented acertain new and useful linprovei'nent in lVziterproofing Composition,and declare the following to be a full, clear, and exact description ofthe same, such as will enable others skilled in the art to which itpertains to make and use the same.

My invention relates to a composition of matter for Waterproofing and anobject of my invention is to provide a waterproofing com-positionparticularly adapted for use on fabric materials such as automobiletops, renting, tarpaulin, fish nets, et eel-era.

A further object of my invention to produce a Waterproofing which willact as a preservative and not ileleteriously affect the fabric ormaterial on which it is used,-

but which will increase the tensile strength of the fabric to which itis applied. and will? 'Petroleum distillate 6 parts Gilsonite 3 partsFish oil--- lpart The best results are secured, however,

from a mixture in proportions approximately as follows:

Petroleum listillate, 58.8% Gilsonite 35 0 Fish oil 6.2%

A black pigment, preferably in the form .of lamp black may be addedwhich will latented lion. 9, 1920.

give the material coated a. lustrous blaelr i'llllSll. This pigmentshould be added in the proportion of approximately "07% to 5th of 1% andthe preferred formula -Wit-l the addition of lamp blackn'ould be lows:

Petroleum distillateuifi Gilsonite 39 Fish oil 6.1

Lamp black 1% Each of these ingredients may rary widely in quality:Petroleum distillate "Therefore, I do not wish to be understood asconfining myself to the definite propor tiorr-hereinabove set forth. Thedistillate mineral oil used might Vary from to gilsonite from 20% to 46%and fish oil from P1 to 10% of the mixture.

The black pigment, if? used, would be of small quantity, "for althoughit possesses aterproofingqualities, its principal purpose is asacoloring; and for producing a finish,-

The ingredients composing this co1npound Wodld be thoroughly mixed,preferably at a temperature of :lrom 50 to 70 clegrees C. This mixturewould preferably be applied to a fabric material such as touting,

r automobile tops, by being" spread thereon with a brush. 1* ish netsand metal parts might be immersed in a vat of the'liquid. The bestresults would be secured at a temperature somewhat above 50 degrees C.

The number of coats or applications would depend on thecharacter or theWork for which the material was intended and the Weave of the fabric. Ifthe composition were applied to a loosely Woven, open-mesh fabric, moreapplications would be required to build up a Waterproof coat. On theother hand, a closely Woven fabric would require less.

Pantasote, used for automobile tops, possess'es a finished surface andclose weave, when coated with the com osition and dries with a lustrousblack finis I The composition dries better outpf doors. Good results arenot obtained under the influence-of artificial heat, unless there is adistinct air circulation.

This composition has been found to increase thept'ensile stren h ofcotton cloth and burla approximate cent; F a rics so treate resist theaction of weather and saltwater and are found to resist the action ofacid fumes for days at a time. The pliable quality of the fabric is inno way damaged; the coating will I not crack or break and fabric sotreated may be rolled or twisted without injury to the waterproofingapplied thereto.

Metal parts may preferably be coated with this composition by beingimmersed therein and Will be found to be resistant to acid fumesthereafter, as well as the action of the weather-and salt water.- Metalis in no way corroded by the action of'the composition.

This composition when used on hulls or decks of boats or other woodenmaterial,

.might mu contain distillate in as low a proportion as 20% to 50%, witha correone hundred per I spending hiher percentage of gilsonite,

with practica 1y no variation in the fish oil as above set forth.

I claim: e

1. The within-described waterproofing composition, consistingofsubstantially six parts of petroleum distillate,'three parts ofgilsonite, and one part of fish oil.

2. The within-described waterproofin -composition, composed of mineraloil, vsonite, fish oil, suhstantiall as set forth.

waterproofing composition consisting of about 59% pe-;

troleum distillate about 35% gilsonite, about 6%}fish oil, and a smallquantity of lamp bla 5. .The Within-described waterproofing composition,composed of petroleum distillate 58.8 percent, gilsonite 35 per cent,

fish oil 6.1 per cent; and lamp black .1 per cent, substantially "asdescribed.

In testimony whereof I sign this specification; v
